Research Faculty and Staff
George Hussey, PhD
Dr. Hussey is an Assistant Professor in the Department of Pathology at the University of Pittsburgh. His research interests include an in-depth understanding of the molecular mechanisms of matrix-induced constructive remodeling and immune modulation, with the broad goal of identifying and characterizing molecular targets to bias these responses. Dr. Hussey conducted his doctoral research in the Department of Cancer Biology at the Cleveland Clinic Lerner Research Institute, his postdoctoral training in the Department of Biochemistry at the Medical University of South Carolina, and in Dr. Stephen Badylak’s laboratory at the McGowan Institute for Regenerative Medicine.
Neill Turner, PhD
Neill Turner is a Research Assistant Professor at the University of Pittsburgh. He is investigating the role of decellularized extracellular matrix (ECM) in limb and muscle regeneration. He has extensive experience studying vascular biology and cardiovascular tissue engineering. Neill’s particular interest is in the role dynamic forces play in the control of cell differentiation and cellular recruitment to sites of injury. Neill completed his doctorate at the UK Centre for Tissue Engineering at the University of Manchester. Here, he investigated how cyclic stretching mediates differentiation of adult progenitor cells down smooth muscle, osteogenic and adipogenic lineages. In addition, Neill investigated the endothelialization of artificial vascular grafts and the effects of extracellular matrix substrata and shear stress on endothelial cell attachment and retention, leading to the development of a type VIII collagen-coated, endothelialized polyurethane graft.
Scott Johnson, MS
Scott Johnson is a research scientist in the Badylak laboratory. He received his master’s degree from Bowling Green State University studying Evolutionary Biology. Scott participates in a broad array of projects involving customized ECM devices, bioreactor-based cell culture, and preclinical studies. He is particularly involved in the REPAIR: Regenerative Electronic Platform through Advanced Intelligent Regulation project funded by the Defense Department.
Li Zhang, MD, MS
Li Zhang is a research scientist in the Badylak laboratory. She graduated from Beijing Medical University in China. She is involved in a variety of projects to study cell compatibility of ECM and is particularly involved in whole organ engineering – especially the whole liver extracellular matrix scaffolds as a potential replacement for liver transplants.
Julia Hart is the supervisor of the Histology Core Laboratory for the McGowan Institute for Regenerative Medicine. She received her master’s degree from Duquesne University. In the past, she has worked with laboratories that service the forensic and pharmaceutical sectors. She currently performs the processing, embedding, cutting, and staining of histology samples for laboratories across the University of Pittsburgh.
Salma Osama El-Mossier is a research scientist in the Badylak lab. She graduated with a degree in biotechnology from the German University in Cairo, Egypt. Her research interests are focused on studying epimorphic regeneration in salamanders and subcellular trafficking of IL-33.
Post Doctoral Fellows
William D’Angelo, PhD
William D’Angelo completed his doctoral training at the University of Southern Mississippi, where he studied the acquisition of antiviral and inflammatory immune responsiveness during differentiation of embryonic stem cells. His research interests include exploring the roles of exosomes in regulation of immune responses and in recruitment and differentiation of stem/progenitor cells during constructive remodeling.
Marley Dewey, PhD
Marley Dewey is postdoctoral fellow in the Badylak Laboratory. She completed her doctoral training at the University of Illinois Urbana-Champaign, where she modified mineralized collagen scaffolds for large-scale bone regeneration and investigated the in vitro immune response, mechanics, bacterial response, and multiple cellular responses within this system. Her research interests include investigating the immune and various cell responses of soft tissue systems to biomaterials, including how matrix-bound nanovesicles impact optic nerve regeneration.
Anjani Ravindra, MD
Anjani Ravindra received her MD from the University of Pittsburgh School of Medicine. During her pediatric pulmonology fellowship at Children’s Hospital of Pittsburgh, she joined the Badylak laboratory and has continued as a postdoctoral fellow. She is developing an ECM-based tracheal bioscaffold which ties in with her clinical interest in pediatric lung transplantation.
Arthi Shridhar, PhD
Arthi Shridhar is a postdoctoral fellow in the Badylak laboratory. Arthi completed her doctoral training at the University of Western Ontario in Canada, where she focused on the development of tissue-specific extracellular matrix derived scaffolds in combination with adipose-derived stem cells, for musculoskeletal tissue regeneration. She is currently the liaison for the BD/CR BARD relationship, and her research interests include the immune-modulatory effects of matrix-bound nanovesicles and the use of ECM-based platforms for skeletal muscle regeneration in pre-clinical and clinical studies.
Héctor Capella Monsonís, PhD
